Attention spans are definitely down. I know I read a lot more shorter format myself. And there's actually a lot of data on it.

I certainly don't feel compelled to write for SEO or eyeballs. But easy and quick doesn't need to mean bad and is often OK for day-to-day stuff.

Most things I publish are in the 800-1000 word range. These days I'll tend to go multi-part rather than the 3K-5K stuff I used to do fairly routinely.

There's nothing wrong with the listicle format, but as another poster described, the problem with 'X myths about Y' is that they tell you that the myth is wrong... Without telling you what is right.

I'm thinking it's not linear, ordered, etc. So the list works.
